1. INTRODUCTION
1.1 PURPOSE OF THIS MANUAL
The purpose of this Manual is to provide information of new User Interface board OMEGA.
1.2 WARNINGS
All work with open appliances must be done with the mains supply disconnected.
The intervention on electrical equipment should only be performed by qualified
personnel.
Before working on a device, check the efficiency of the system housing through means of
appropriate equipment. As an example, refer to the indications described / illustrated in
the portal Electrolux Learning Gateway (http://electrolux.edvantage.net).
After intervention, carry out electrical safety tests and check the correct
operation of all safety devices.
In the case of manipulation / replacement of the PCB, use the ESD kit (Code 405 50 63-
95/4) to prevent electrostatic discharge damage the circuit board see SB No. 599 72 08-09

9. FUNCTIONS AND USE OF VISION VCU INTERFACE
9.1 INITIAL OPERATION (START-UP PROCEDURE)
The start-up procedure of the appliance is divided in 2 parts. If a factory test was done the appliance reacts
after plug-in as described for first connection with mains.
9.1.1 FIRST CONNECTION WITH THE MAINS
After the first connection with the mains (resp. after connection with mains after factory test) the following
sequence starts:
1. Displaying manufacturer logo for
7 seconds.
2. For the next 7 seconds displaying software version from
Firmware OUI
Configuration OUI
Firmware PB and
Working hours counter (only value)
The indication is the same like settings menu “basic settings” item “service”.
3. Set language in the same way as in basic settings menu. The selected language will be stored in flash
memory. The user has to do later changes in the menu “basic settings”.
4. The next point is to set the display contrast. This is the same flow as is described in chapter “basic
settings” item “display contrast”. The value will be stored in flash memory. All later changes can be
done in menu “basic settings”
5. After setting the display contrast, set display brightness. This is the same flow as is described in
chapter “basic settings” item “display brightness”. All later changes can be done in menu “basic
settings”
6. Afterward set of ToD, same way as is described in chapter “basic settings” item “set time of day”.
This setting synchronizes the RTC. Then the RTC delivers a ToD value –even a short time after
power failure. All later changer of ToD can be done in menu “basic settings”.
7. Interface in OFF_STATE with ToD indicated resp. also residual heat indication (if activated and
value for available).
9.1.2 ANY FURTHER CONNECTION WITH THE MAINS
Any further connection with the mains affects the following sequence:
1. Displaying manufacturer logo for 7sec…
2. Display software versions and working hours counter.
3. ToD setting –only if a ToD value is not available anymore (from RTC).
4. Interface in OFF_STATE with ToD indicated resp. also residual heat indication (if activated
andvalue for available).
Valid for both connections:
As long as manufacture logo is displayed it is possible to enter the factory test. The workflow of the factory
test is described in chapter Factory Test.

Technical Support - BSP 19/27 599 73 44-69 Rev. 00
9.2 OFF_STATE
When the oven is switched off, the time of day (ToD) is displayed and, in case of residual heat in oven, also
the temperature bar for residual heat indication. Depending of application also with real temperature in °C
(e.g. for steamer applications necessary). ToD can be switched off to set the display completely dark. This
has to be done in basic settings menu.
9.2.1 DAY /NIGHT BRIGHTNESS
The OUI reduces the brightness of ToD indication in OFF_STATE in the timeframe 22:00 until 06:00 o'clock
to level 1. After customer interaction the OUI stays 5seconds in last used brightness (day brightness).
9.2.2 RESIDUAL HEAT DISPLAY
Decreasing bar - same animation and position as heating indication in ON_STATE.
At steamer applications in real degrees without state bar.
Disappears if cavity temperature less than 40°C.
Animation shows a relation between cavity temperature/oven set temperature.
9.2.3 STANDBY-STATE
To reach the standby-state, the appliance must be in the off-state. Afterwards press once more
the on-/off-key . The main menu is displayed.
Off State
Standby-state / Main Menu
This is the starting point for all functions.
If no key is pressed, after 2 minutes, the appliance is changed automatically from standby-state in to off-
state.

Technical Support - BSP 20/27 599 73 44-69 Rev. 00
10. DEMO MODE
The Demo Mode is implemented for demonstrating the functionality of the appliance in show rooms or
shops, on trade fairs etc. without energy consumption behind. The user can find out the complete
functionality of the OUI but for security reason the loads (heating elements) stays off.
10.1 WORKFLOW TO ACTIVATE / DEACTIVATE DEMO MODE
To activate / deactivate the demo mode:
1. From OFF_STATE keep the main switch pressed for at least 5 seconds.
2. The user interface enters STAND_BY for 5sec. and jump back to OFF_STATE. Buzzer sounds
(Tone_1)
3. Then release the main switch and press the combination KEY_MODE + KEY_FAVOURITE
for two seconds .
4. Buzzer sounds (3 x Tone_1) and
• The Demo Mode is active now. Indication of Demo Mode in left upper corner with
Layout_18 and Icon10_1.
• The demo mode is deactivated now. No indication of Icon10_1.
11. SERVICE MODE (FACTORY TEST)
The factory test is implemented to check all electrical components of the appliance at the end of the
production line. This test can only be activated as long as manufacture logo is displayed.
This function can also be used by the Service for troubleshooting.
11.1 SERVICE MODE ACTIVATION
Activation will be done by pressing KEY_HOME + KEY_MODE simultaneous for 2seconds until
the buzzer sounds (Tone_1). After activation of the factory test the display starts with the first activated loads
of main cavity.
11.2 SERVICE MODE DEACTIVATION
Pressing the KEY_MAIN together with another key you can terminate the factory test.
The factory test should be deactivated after 5 minutes without any user interactions
If the factory test was done, the user can deactivate the factory test with the KEY_MAIN . After that the
oven has to be disconnected from the mains.
